Neuronal aging causes mislocalization of splicing proteins and unchecked cellular stress.
Nature neuroscience · 2025 · 28(6): 1174-1184
Aging is one of the most prominent risk factors for neurodegeneration, yet the molecular mechanisms underlying the deterioration of old neurons are mostly unknown. To efficiently study neurodegeneration in the context of aging, we transdifferentiated primary human fibroblasts from aged …

Localized molecular chaperone synthesis maintains neuronal dendrite proteostasis.
Nature communications · 2024 · 15(1): 10796
Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted protein folding. However, this is challenging in neuronal projections because of their polarized morphology and constant synaptic proteome remodeling. Using high-resolution fluorescence microscopy, we discover that hippocampal and spinal …

Localized synthesis of molecular chaperones sustains neuronal proteostasis.
bioRxiv : the preprint server for biology · 2024
Neurons are challenged to maintain proteostasis in neuronal projections, particularly with the physiological stress at synapses to support intercellular communication underlying important functions such as memory and movement control. Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted …

A phage nucleus-associated RNA-binding protein is required for jumbo phage infection.
bioRxiv : the preprint server for biology · 2023
Large-genome bacteriophages (jumbo phages) of the <i>Chimalliviridae</i> family assemble a nucleus-like compartment bounded by a protein shell that protects the replicating phage genome from host-encoded restriction enzymes and CRISPR/Cas nucleases. While the nuclear shell provides broad protection against host nucleases, …

The <i>Thermus thermophilus</i> DEAD-box protein Hera is a general RNA binding protein and plays a key role in tRNA metabolism.
RNA (New York, N.Y.) · 2020 · 26(11): 1557-1574
RNA helicases catalyze the ATP-dependent destabilization of RNA duplexes. DEAD-box helicases share a helicase core that mediates ATP binding and hydrolysis, RNA binding and unwinding. Most members of this family contain domains flanking the core that can confer RNA substrate …

Context-Dependent and Disease-Specific Diversity in Protein Interactions within Stress Granules.
Cell · 2018 · 172(3): 590-604.e13
Stress granules (SGs) are transient ribonucleoprotein (RNP) aggregates that form during cellular stress and are increasingly implicated in human neurodegeneration. To study the proteome and compositional diversity of SGs in different cell types and in the context of neurodegeneration-linked mutations, …
